METHOD OF MEKING SHINGLE-STRIPS AND BLANKS THEREFOR.

Specification 0! Letters Patent.

Application filed. August 15, 1907. Serial No. 388,721.

Blanks Therefor, of which the following is a s ecification.

his invention relates to roofing strips composed of flexible waterproof material, and adapted to be laid 1n overlapping courses, each strip constituting a member of the covering of a roof or other surface of' a building.

The invention has for its object to provide a roofing stri or member which, when assembled wit other strips, will have a continuous edge and a notched or slotted edge, the latter resembling a strip or row of shingles.

The invention consists in the improved method of making shingle strips, and in a shingle stri blank produced in practicing said metho all as hereinafter described.

- Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side view of a portion of my i'mproved shingle strip blank. Fig. 2 re resents a view showing the blank illustrate in Fig. 1, longitudinally subdivided into two complete shingle strips. Fig. 3 re resents a view showing a series of shing e strips as laid upon a roof.

The same letters of reference indicate the same arts in all the figures.

A s 'ngle stri made by racticing my improved metho is compose of a suitableflexible waterproof material in the form of an elongated, flexible strip at having transverse slots or notches b bisecting one edge of the strip and extending therefrom partly across the strip, the length of the slots being sufiicient to extend across the portion of the str ipxwhich is exposed when the strip is laid. e slots are substantially parallel with each other, and the edges of each slot are substantially parallel. The slots and the edge of the strip bisected thereby, extending across the exposed surface of the strip, form the abutting or o posed edges 2 2 and the lower ends 3 o a series of shingles. The opposite edge portion 4 of i the strip, which in place on a roof is covered andconcealed by a stri aboveit, is' continuous, and connects -t e said shingles as shown in Figs. 2 and 3. When a plurality of strips are laid upon a roof, as indlcated-in Fig. 3, the slotted overlaps the connecting portion 4 of the next strip below it, so that the connecting portions of the strips are-concealed,'and the assemblage of strips gives the effect of an ordinary shingled roof, the exposed portion of each stri presenting the appearance of a course of s ingles.

a is as f0 ows: Taking a sheet a of twice t width of one of the strips a, I form between the longitudinal edges thereof, transverse slots 1), the ends of the slots bein between the edges of the sheet so that both ongitudinal edges are continuous. I then subdivide the slots along the dotted line 5-5, thus forming the elongated lower ends 3 of two shingle stri s, as indicated in Fig. 2. By this metho I am enabled to produce the described shingle strips rapidly and economthe result of the first ste in the method hereinbefore described, an is adapted to be by the second step of sai method, which mvolves onl the slmple operation of making a straight lbngitudinal out between the ends of the slots. The said blank may be put on the market as an article of manufacture, and may be converted into complete strips by the user, no s e'cial mechanism being required to form the ongitudinal cut. The blank may be rolled to form a compact package for trans ortation and storage.

I c aim:

1. A shingle strip blank composed of an elon ated sheet of flexible waterproof macontinuous, said blank being adapte to be converted 1nto two operative shingle stri s by severing it lengthwise between the on s of the slots. U

2. A shingle strip blank of indeterminate My im roved method of making the strips e ically. The sheet a with its transverse slots." 1) constitutes a shingle strip blank, whlchis converted into two com lete shingle 's tripsportion of each strip the sheet longitudinally between the ends of teria, having transverse slots between its edges, the ends of the slots being between the edges of the sheet so that said ed es are length composed of an elongated sheet of severing it lengthwise between the ends of flexible waterproof material, havin transthe slots.. 10

' verse slots between its ed es, the en s of the In testimony whereof I. have aflixed my slots being between the eages of the sheet s0 signature, in reseneeof two witnesses.

5 that said edges are continuous, said blank FR DERIOK C. OVERBURY.
